A GitOps-driven deployment system designed to deliver containerized services safely, observably, and with deterministic rollback.
This project demonstrates how application delivery can be controlled entirely through Git, using continuous reconciliation, health-based rollouts, and automated recovery - without relying on manual intervention or imperative deployment workflows.
Modern teams deploy containerized services frequently, but deployment safety and recovery are often inconsistent.
This project focuses on the delivery system, not the application itself. It exists to demonstrate:
- Git as the single source of truth for deployments
- Continuous reconciliation of desired state
- Health-driven rollout validation
- Deterministic rollback via version control
- Clear separation between build and deployment responsibilities
The application components are intentionally minimal and exist only to make deployment behavior observable.
This project follows a few strict principles:
-
Intent over tooling The system is defined by behavior, not by specific platforms or vendors.
-
Declarative over imperative Desired state is expressed in Git and continuously reconciled.
-
Failure as a first-class concern Rollbacks are expected, automated, and demonstrable.
-
Visibility without access Deployment state should be understandable without direct cluster access.
At a high level, the system consists of:
- A minimal backend service that exposes health and deployment metadata
- A static frontend that renders operational state
- A CI pipeline that builds immutable artifacts
- A GitOps workflow that applies and reconciles desired state
Application services act as deployment probes rather than feature-complete products.
- Stateless and containerized
- No database or external dependencies
- Exposes health and metadata endpoints
- Used to simulate successful and failed deployments
The backend exists solely to produce deterministic signals for rollout validation.
- Static, read-only, single-page
- Fetches backend metadata
- Displays version, commit, and health status
- Acts as an operational status surface
The frontend is not a user interface - it is an observability aid.
Continuous Integration:
- Builds immutable container images
- Tags artifacts using version control metadata
- Updates declarative deployment definitions
Continuous Delivery:
- Reconciles cluster state from Git
- Applies rolling updates
- Blocks unhealthy rollouts
- Supports rollback through Git history
There are no hidden or manual control paths.
- Databases or persistent storage
- Authentication or authorization
- Business logic or user workflows
- Autoscaling experiments
- Custom dashboards or UI frameworks
- Long-running or always-on infrastructure
Restraint is a deliberate design choice.
This project is designed to be:
- Cloud-agnostic
- GitOps-engine agnostic
- Runnable on managed or self-hosted Kubernetes
- Safe to provision and fully tear down
Infrastructure is treated as disposable.
This repository is intended to be:
- Read to understand system design
- Deployed to observe rollout behavior
- Broken on purpose to demonstrate recovery
- Rolled back using version control
It is not intended to be used as a production template.
